Volume and channel controls can be individually set on the headphones for better sound, and Center-Lock auto tuning automatically adjusts to the transmitter with a touch of a button, and can be reset with a second touch.

Roam up to 300 feet from the transmitter and still hear your music, through walls, ceilings, even outdoors. Soft cloth-covered earpads and headband cushion keeps your head comfortable even during long listening sessions. For multiple listeners, simply add a second set of headphones and both can listen in on a single transmitter.

These headphones can run up to four hours before needing to be recharged. When the power runs out, simply drop them into the cradle recharger. This can be done up to 500 times without any "memory" effect to degrade your runtime.

For an incredibly versatile wireless solution for private listening to your favorite music, Sennheiser's RS 45 wireless headphones provide all the power you need.

Good design, decent sound quality, static, no isolation   March 12, 2002

I bought these to be able to watch tv while my girlfriend is studying by my side. Connection is easy as 1-2-3. Immediately picked up the sound channel and produced nice sound. If you are into serious sound, then you should forget about wireless in the first place. You can wander around between the rooms and still have the reception. The thing i didn't like was this "900 MHz" technology. Just like in cordless phones there is interference and occasional noise. Funny thing - regular TV broadcast gave less noise then watching "Run Lola Run" on DVD. Go figure...
Yes, one more thing: sitting next to me on the couch my girlfriend said that she could hear sound coming pretty clear out of external earphone covers and kept asking me to turn it down. Even she was surprised when she found out that the volume level was pretty low. I'm thinking of returning them.

Good design, decent sound quality, static and no sound shield.


Disappointing   February 15, 2002

I bought these for home and work, thinking I'd be able to listen to the MP3s on my computer while roaming from room to room.

Well, forget that. Despite the claims that you can hear your music through "walls and ceilings", the reality is that even one or two thick walls will block clear reception. And I don't know where they came up with that "300 foot" range for the reception, but it's just not true. In addition, the power cord and audio jack are way too short, limiting your ability to position the transmitter to where it might do some more good. If you're looking to listen to your TV or stereo from across the room, this might be the product for you, but if you want to listen to music in the backyard, you'd be better off with something else.


Wireless can't be perfect   November 7, 2003

I bought this product to be able to watch tv without disturbing my wife who doesn't like background noise when she's reading. For that purpose the Sennheiser RS-45 is great. I can sit wherever and move freely without being constrained by a cord.

But don't expect too much. If you move around, there will be few disturbances in reception, just as there would be if you are moving around with a portable radio. Next room the reception is not too great, so you can forget about going to the basement with the headphones if the transmitter is somewhere else.

In short: if you're looking for perfect sound quality, get regular headphones with a cord. If it's more important for you that you can move around a bit, the Sennheiser RS-45 is a good option.


Bloody awful   September 15, 2002

I waited the required 24h before eagerly popping these phones on and loading up some Maceo Parker, only to be horribly disappointed.

The sound quality is fine (although noticeably worse than that of lower-priced wired alternatives, such as my recently-broken Beyerdynamic DT231 set, which I'll soon be replacing). However:

Every 45-120 seconds, the music would just cut out - period. A press of the tune button would restore the signal, albeit after 1-2 seconds of unpleasant noise, but this is completely unacceptable.

FYI, I was seated less than 4ft from the transmitter; I tried it on both channels; I switched off all electronic devices in the room and the two next to it, other than my CD player, amp and the transmitter itself. In other words, there's no excuse for the shocking performance.

For me, the applications of this product were a) for use during exercise/cooking/guitar practice and b) for relaxed evening listening. During neither do I want to have to retune the damned headphones every minute. It ruins the flow of any piece of music, and renders the units almost totally worthless. It's a real shame.

They're going back to the dealer tomorrow. Avoid this product.
